自学python入门，请问我如何才能取出status对应的值？

{'data': [{'bindTime': '2021-07-13 17:38:38',
           'coord': None,
           'firstBindTime': '2021-07-13 17:38:38',
           'hwVersion': '1',
           'mac': 'C8-AA-55-14-D3-E8',
           'position': None,
           'productForm': 'Terminal',
           'productName': '音响',
           'productType': '8Ω,50W,IP、4G、AC 220V',
           'id': '2021070105690',
           'status': 'online',
           'swVersion': '12.5.1.5'}],
 'resultCode': '200',
 'resultMsg': '操作成功',
 'successful': True}

dict1 = {'data': [{'bindTime': '2021-07-13 17:38:38',

           'coord': None,

           'firstBindTime': '2021-07-13 17:38:38',

           'hwVersion': '1',

           'mac': 'C8-AA-55-14-D3-E8',

           'position': None,

           'productForm': 'Terminal',

           'productName': '音响',

           'productType': '8Ω,50W,IP、4G、AC 220V',

           'id': '2021070105690',

           'status': 'online',

           'swVersion': '12.5.1.5'}],

 'resultCode': '200',

 'resultMsg': '操作成功',

 'successful': True}

print(dict1['data'][0]['status'])

 

a =  {'data': [{'bindTime': '2021-07-13 17:38:38',
